Methods Cell Biol 2020 10;157:185-221. Epub 2019 Dec 10.

Department of Veterinary Surgery and Radiology, West Bengal University of Animal and Fishery Sciences, Kolkata, West Bengal, India. Electronic address:

The inability of cartilage tissue to self-heal due to its avascular nature often leads to conditions such as osteoarthritis, traumatic rupture of cartilage, and osteochondrosis. The cartilage provides cushioning effects between the joints and avoids bone frictions. The extracellular matrix (ECM) of cartilage consists predominantly of collagens, elastin, proteoglycans and glycoproteins. Read More

Int J Mol Sci 2019 Dec 7;20(24). Epub 2019 Dec 7.

ISPAAM, National Research Council, 80147 Naples, Italy.

Osteochondrosis is a failure of the endochondral ossification that affects developing joints in humans and several animal species. It is a localized idiopathic joint disorder characterized by focal chondronecrosis and growing cartilage retention, which can lead to the formation of fissures, subchondral bone cysts, or intra-articular fragments. Osteochondrosis is a complex multifactorial disease associated with extracellular matrix alterations and failure in chondrocyte differentiation, mainly due to genetic, biochemical, and nutritional factors, as well as traumas.

Starting with the smallest functional unit, the spinal segment including the centrally located intervertebral disc, the spine and pelvis including the sacroiliac and hip joints form a functional unit. The discs play an important role in the complex interaction between disc, osseous and ligamentous structures and the adjacent muscles. Disc pathologies are very frequently associated with changes of the adjacent endplates of the vertebral bodies and can be depicted at an early stage using magnetic resonance imaging (MRI). Read More

Benign bone tumours of tibial tuberosity clinically mimicking Osgood-Schlatter disease: a case series.

Int Orthop 2019 11 11;43(11):2563-2568. Epub 2019 Sep 11.

Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, Iran University of Medical Sciences, Tehran, IR, Iran.

Introduction: Osgood-Schlatter disease (OSD) is a traction apophysitis of the tibial tubercle and a common cause of anterior knee pain in growing adolescents. A variety of benign neoplasms can also cause bony prominence over the tibial tubercle in adolescents that might clinically imitate OSD. Therefore, the differential diagnosis of tumours mimicking OSD is critical and considered the primary goal of this study. Read More

Double-Stranded RNA Is a Novel Molecular Target in Osteomyelitis Pathogenesis: A Translational Avian Model for Human Bacterial Chondronecrosis with Osteomyelitis.

Am J Pathol 2019 10 2;189(10):2077-2089. Epub 2019 Aug 2.

Center of Excellence for Poultry Science, University of Arkansas, Fayetteville, Arkansas; Cell and Molecular Biology Program, University of Arkansas, Fayetteville, Arkansas. Electronic address:

Osteomyelitis remains a serious inflammatory bone disease that affects millions of individuals worldwide and for which there is no effective treatment. Despite scientific evidence that Staphylococcus bacteria are the most common causative species for human bacterial chondronecrosis with osteomyelitis (BCO), much remains to be understood about the underlying virulence mechanisms. Herein, we show increased levels of double-stranded RNA (dsRNA) in infected bone in a Staphylococcus-induced chicken BCO model and in human osteomyelitis samples. Read More

The Passive Mechanical Properties of Muscles and Tendons in Children Affected by Osgood-Schlatter Disease.

J Pediatr Orthop 2020 Apr;40(4):e243-e247

Graduate School of Education, Okayama University, Kita-ku, Okayama, Japan.

Background: Osgood-Schlatter disease (OSD) is a sports-related disorder involving apophysitis, which affects the tibial tuberosity. The identification of factors related to OSD is important for its prevention and early recovery from the disease. This study aimed to compare the passive mechanical properties of the muscle-tendon unit in children affected by an OSD and healthy children, by using ultrasound real-time tissue elastography.

Growth patterns, metabolic indicators and osteoarticular status in the Lusitano horse: A longitudinal study.

PLoS One 2019 17;14(7):e0219900. Epub 2019 Jul 17.

Centre for Interdisciplinary Research in Animal Health, Faculty of Veterinary Medicine, University of Lisbon, Lisboa, Portugal.

Development of a healthy musculoskeletal system is of high concern for horse breeders and users. A longitudinal field study was performed in order to: (i) evaluate growth patterns and long-term changes on bone quality, bone metabolism, growth factors and metabolic variables in the Lusitano horse; and (ii) retrospectively assess whether these changes were related with radiographic findings regarding osteochondrosis-like lesions (OC) at the onset of training. Thirty-four Lusitano foals born and raised at four stud-farms, were periodically weighed (BW), and measured (withers height-WH) from birth to 36 months of age. Read More

Idiopathic Genu Valgum and Its Association With Obesity in Children and Adolescents.

J Pediatr Orthop 2019 Aug;39(7):347-352

Shriners Hospitals for Children.

Background: Obesity as a cause of lower extremity deformity in children has been well established. This deformity is most often seen as tibia vara, however, at our institution we have observed more obese children and adolescents over age 7 years with excessive or progressive idiopathic genu valgum. Our hypothesis is that children with idiopathic genu valgum have high rates of obesity which impact the severity of their disease. Read More

Bisphosphonate use in the horse: what is good and what is not?

BMC Vet Res 2019 Jun 24;15(1):211. Epub 2019 Jun 24.

Department of Veterinary Physiology and Pharmacology, College of Veterinary Medicine and Biomedical Sciences, College Station, TX, USA.

Background: Bisphosphonates (BPs) are a family of molecules characterized by two key properties: their ability to bind strongly to bone mineral and their inhibitory effects on mature osteoclasts and thus bone resorption. Chemically two groups of BPs are recognized, non-nitrogen-containing and nitrogen-containing BPs. Non-nitrogen-containing BPs incorporate into the energy pathways of the osteoclast, resulting in disrupted cellular energy metabolism leading to cytotoxic effects and osteoclast apoptosis. Read More
